The Effect of Artificial Crossing on The Yield of Several Corn Varieties (Zea mays L.)
Abstract
Corn is one of the food crops cultivated in Indonesia. Efforts to increase corn production can be done in various ways, one of which is by artificial crossbreeding. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Teuku Umar University from November 2020 to March 2021. The experimental design used in the study was a non-factorial Randomized Block Design (RAK) with 3 replications. The factors observed for Corn Varieties in the vegetative phase were: (1) Pulut Uri (P), (2) Srikandi Kuning (K), and (3) Srikandi Ungu (U). If the F test is significantly different, it is continued with the smallest significant difference test (LSD) with a level of 5%. The results of the study showed that the artificial crossbreeding of U♀ x P♂ (Srikandi Ungu♀ x Pulut Uri♂) was significantly different in the parameters of the diameter of the husked cob and the length of the cob without the husk. Artificial cross U♀ x P♂ x K♂ (Purple Srikandi♀ x Pulut Uri♂ x Yellow Srikandi♂) long cob with husk.
